Between 1952 and 1976 192 consecutive cases of penile epidermoid carcinoma were seen at the Instituto Nacional de Enfermedades Neoplascias of Lima, Peru. The mean age when the disease developed was 60.5 years, with a peak incidence between 60 and 64 years (32 patients). No correlation was observed between extensive lesions of the shaft of the penis to high pathological staging. Clinical examination of the inguino-crural nodes is not a good criterion for staging. We wait six weeks after eradication of primary lesion before lymphadenectomy. No correlation exists between grade and pathological stage. When no lymph node was positive, the overall survival rate over five years was 90.69%; when lymph nodes were metastasized there was an overall survival rate over five years of only 9.39 percent. The coefficient of cancer versus noncancer cause of death was 1.25 for pathological stage I, 3.09 for pathological stage II, 4.83 for pathological stage III, and 10.000 for pathological stage IV. Our patients did have advanced disease, as 57.14% of deaths occurred at two years and 25.21% more at five years.
1952年至1976年间，秘鲁利马国家肿瘤研究所共收治了192例阴茎表皮样癌患者。发病时的平均年龄为60.5岁，60至64岁年龄段发病率最高（32例）。阴茎体广泛病变与高病理分期之间未发现相关性。腹股沟 - 股淋巴结的临床检查不是分期的良好标准。我们在原发灶切除后六周再进行淋巴结清扫术。分级与病理分期之间不存在相关性。当没有淋巴结转移时，五年总生存率为90.69%；当淋巴结发生转移时，五年总生存率仅为9.39%。病理I期癌症与非癌症死因系数为1.25，病理II期为3.09，病理III期为4.83，病理IV期为10.000。我们的患者确实患有晚期疾病，因为57.14%的死亡发生在两年，五年时又多了25.21%。
